Abstract
A passive transponder including an antenna for receiving an input signal and transmitting an output and a memory for storing the data received by the transponder from an interrogator. The transponder can operate in either a read mode or a programming mode. The transponder includes an integrity circuit for indicating the integrity of the input signal, a monitoring circuit that monitors a characteristic of a host and an impedance modulator that prevents the overmodulation of the output signal. A characteristic sensor of the transponder can be calibrated by the method of placing the transponder in a liquid bath, measuring the value of the bath with the transponder, outputting the temperature value measured by the transponder, receiving the output signal and computing the temperature value of the bath, comparing the computed value of the bath with the known value of the bath and storing the difference between the computed value and the known value in a predetermined memory location in the transponder.
